Abstract
Each of a plurality of clock generation units has a clock driver which generates a clock signal in accordance with a reference clock, and a supplying unit which supplies the reference clock to the clock driver. The supplying unit supplies the clock driver, in a case where another clock generation unit is already attached to a clock signal generation device at a time the clock generation unit to which the supplying unit belongs is attached to the clock signal generation device, with a clock signal generated by the clock driver of the another clock generation unit as the reference clock during a predetermined time. The clock driver makes a clock signal to be generated follow the supplied reference clock.
